FORM FOR WRAPPING FOLDING BOXES.

Specification of Letters Patent. Faten-tea Dec, 21, 192() Applicationfiled October 23, 1920. Serial N0..418,883.

To all whom it may concern:

Be it known that I, HERBERT H. WAGNER, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented a new and useful Form for Wrapping Folding Boxes, of whichthe following is a specification.

This invention relates to means for supporting a pasteboard box and awrapper therefor during the process of uniting the wrapper to the box.

The object of the present invention is to provide an improved formparticularly adapted to fit into and support the sides of a folding onepiece pasteboard box of the character described and claimed in anapplication filed October 7, 1920, Serial No. 415,413.

It is a further object to provide an improved support for the wrapperand box by the use of which the wrapper is not united to the hingedportion of the box but is left free thereof so that the unitin of thewrapper with the hinged section of the box does not take place until thefolding of the box is accomplished.

The present invention comprises attachments for commercial box-wrappingmachines. It is therefore an object of the invention to provide a formand support which are adapted to be used with such machines without anychange whatever in the construction or operation of the machine.

The present case is the fourth of a series of cases. the first of whichwas referred to above. The second case, Serial No. 418,881, covers theimproved wrapper; the third case, the process of; uniting the improvedwrapper with the improved foldable box is described and claimed in anapplication, Serial No. 418,882.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawings forming part of this specification, with the understanding,however, that the invention is not confined to any strict conformitywith the showing in the drawings, but may be changed and modified solong as such changes and modifications mark no material departure fromthe salientfeatures of the invention as expressed in the appendedclaims.

In the drawings:

Figure 1 is a perspective view illustrating the box and wrapper beforethe uniting thereof.

Fig. 2 is a vertical elevation with the box and wrapper indicated incross section showing the form and the support before the wrapper hasbeen united to the flanges of the box.

Fig. 3 is a vertical transverse section with parts shown in elevationand illustratingthe wrapper flanges in the act of being united to thebox flanges.

Fig. 4t is a top plan view of the form for the box.

Fig. 5 is a top plan view of the block or anvil which provides a supportfor the box and wrapper.

The numeral 6 designates the receptacle portion of the improved box and7 is the cover portion. The receptacle portion has an end flange 10integral therewith and side flanges 11. The cover portion has side andend flanges 12 all substantially alike, therefore designated by the samereference character. Binders l3 join the abutted ends of the flanges ofthe box. Each flange 11 has a tab 14 integral therewith. The flanges andtabs are all separated from the parts of the box to which they areconnected by score lines made by a knife-like implement which cuts intothe fibers of the material of the box.

The cover and receptacle portions are connected by an intermediatehinged portion 8. This hinged portion is substantially rectangular andis joined to the other parts of the box being integral therewith. Creaselines 9 define the hinged portion. Such crease lines are made by a bluntinstrument which compresses the fibers of the material of the boxwithout cutting or breaking the same. The box is designed to be foldedalong both crease lines and is formed with slight continuous taper sothat the cover portion has a suficient width to inclose the receptaclepor tion. The tabs 14- are designed to be folded inwardly so that theywill support the hinged 1 portion of the box when the cover closes thebox.

The wrapper 15 is of paper ornamented in any desirable way and usuallyprovided with advertising matter 011 one side thereof. The i other sideis designed to be coated with mucilage or other adhesive whereby thewrapper is promptly united to the outside of the box so that all visibleportions of the box are covered up. This wrapper comprises end flanges16- and side flanges 17 and 18. Each of said flanges is separated fromadjacent flanges by reentrant cuts and slits. These slits providetriangular tabs 19 intermediate each pair of flanges 17, 18. The flangesof the wrapper have a suflicient width to not only completely cover thecorresponding flanges of the box but they may be pasted over the freeedges of the box flanges and united to the inner walls of said flanges.The end flanges 16 are adapted to be united to corresponding end flanges10, 12 of the box. Each flange 17 of the wrapper is designed to cover aflange 11 of the box and its tab 14. Each flange 18 of the wrapper isdesigned to cover the side flanges 12 of the cover portion of the box.The triangular .tabs 19 of the wrapper are designed to be pasted to theinner wall or face of the hinged portion '8' of the box.

With this understanding of the box and wrapper construction adescription of the parts which form the subject of the present inventionmay be proceeded with. "The numeral 20 designates a stem, 21 a plate and22 fastening elements, such parts being found in the forms of old andwell known wrapping machines and are not further described since theyform no part of the present invention. A block 23 is loosely mounted onthe stem 20 and carries the plate 21. This block may be made of wood andpreferably has a plurality of bores 28 (see Fig {1) permittingiescape ofair in the box when the form and box are joined. The stem 20 is securedrigidly to a plate2i which may be of brassor other metal and has bores(not shown) registering with the bores 23 of the block. Thus the plate 21 and block 23 are loose relative to each other wherebyslightirregularities in formand dimensions Qfthe pasteboard boxes areaccommodated. As seen from Figs. 2 and3 the form is adapted to snuglyfit the interior of the box before ithas been folded to provide a backing or support for the flanges thereof so that the wrapper flanges maybe pressed against the outeh faces of the box flanges without any dangerofcrushing the box. Because of thetaper of the box this form is likewisetapered. In a box of the character and size illustrated in the drawingssuch a taper may amount toone sixteenth of'an inch.

The formwhich hasjust been described works in conjunction with an-anvilor support which w ll now be described. Th s vil is made up of arectangular block 25 which, may be-of Wood having a pair of spaced apartrectangular felt pads 26 se-.

cured upon one face. There is a space 27 left betweenthe felt pads 26,thisspace being wider than the width of the hingedportion18 of-the box.The block 25is mounted uponasupport 28. I

lVhen the boxhas. been thrust upon the thrust into .of the tabs 1?:

form and the form descends within the wrapping machine the wrapper willbe the path of the descending form with its adhesive-coated sideuppermost. The form will press the box against the wrapper when theanvil is encountered and the. felt pads will insure the uniting of thewrapper to that area of the box immediately above said pads. Anintermediate portion of the wrapper indicated by the nu- Ineral 29 inFig. 2 will not be united to the bog because of the space 27 betweenthefelt pa s;

Then the wrapping machine which has rollers 31 mounted upon swingableframes 30 will force the flanges 1 7, 18 of the wrapper against theflanges 11, 12 of the box, this operation being best understood fromFig. 3. N ext the end flanges of the wrapper will be united to thecorresponding flanges of. the box. Finally all the wrapper flanges willbe tucked down inside of the box and secured to the inner wallslof thebox flanges. The last step before folding is the bending the wrappertabs-l tothe inner WELH'VOf the plngied portion 8, this step being doneby H The wrapper isnow united to the box at every point except thesection 29v which isstill freeof thehinged portion. The boxisfoldedalongthe two crease lines 9 and the cover is brought over so that itsthree flanges engage with and close the flanges. of thereceptacleportion6. This folding of .the box stretches the wrapper and lays itagainst the hinged portion 8 whereupon theadhesive coated on the wrappermakes the section 29 unite permanently with portion 8 without anypossibility of splitting or tearing of. the Wrapper along. the hingedlines 9. The provision. of the space between the felt pads bringsaboutthis important result. Were the wrapper to be united to the hingedportion of the box at the same time-it isunited to the other partsthereof, when the box is folded'the Wrapper will frequently, if notalways, split alongv the hinge lines. Thissplitting. of the inwardly andthe joining of wrapper has up, to th P esent time been the chiefobjection to the employment of folding one piece boxes. After theirwrappers split the boxes are p diflicult to market because of theirunsightly appearance.

Boxes made with the present form and anvil are readily salablebecause'thel wrapper will supporting the wrapper and box during theuniting of the same, said means leaving a part of the Wrapper free-ofthe box, said part extending transversely of the wrapper intermediateits ends whereby the uniting is incomplete until the box is removed fromthe machine.

3. In a machine for wrapping folding boxes of the type comprising areceptacle portion, a cover portion and a hinge portion joining theother two portions, an anvil or support adapted to hold the wrapperagainst the underside of the box during the uniting operation, the faceof the anvil in engagement with the wrapper having a break therein,whereby an intermediate section of the wrapper is not presesd againstthe hinge portion of the box.

4. In a machine for wrapping folding boxes of the type comprising areceptacle portion, a cover portion and a hinge por tion joining theother two portions, an anvil or support adapted to hold the Wrapperagainst the underside of the box during the uniting operation; a pair ofspaced apart felt pads provided upon the supporting face of said anvil,the space separating the pads having an extent approximating the area ofthe hinge portion of the box, whereby when the wrapper is being pressedagainst the box an intermediate section thereof will be left free of thehinge portion of the box.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature.

HERBERT H. WAGNER.
